PRS frequency domain resource mapping method, device and storage medium

Abstract

Embodiments of the present application provide a PRS frequency domain resource mapping method, device, and storage medium, which are used to solve the problem of coordination of reference signal resources between different standard networks when cells of different standard networks are deployed in the same frequency band to send PRS. Wherein, the method includes: the network device obtains the information of the first frequency point and the PRS configuration information corresponding to the PRS, and sends the information of the first frequency point and the PRS configuration information corresponding to the PRS to the terminal device through auxiliary information, and the terminal device receives The received auxiliary information determines the resource mapping position in the frequency domain when the PRS is sent and received, and receives the PRS sent by the network device of the second standard at the resource mapping position.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a PRS frequency domain resource mapping method, device and storage medium. Background technique [0002] With the continuous development of communication technologies, communication between terminals and network nodes has become a common communication between devices. It is more and more important for a network node to locate a terminal, or for a terminal to request a location service to implement a specific application. In the fifth generation mobile networks (5th generation mobile networks or 5th generation wirelesssystems, 5G), the new air interface (new radio, NR) will have higher requirements for positioning accuracy. Similar to the traditional long term evolution (LTE) system, the 5G system will also use a positioning reference signal (positioning reference signal, PRS) to position the terminal. [0003] For the 5G system, operators can deploy cells o...
